This Dripless Inc. 125-138 is a classic 10 oz skeleton-style caulk gun utilizing a hex rod mechanism.

• Design & Function: The "skeleton" frame makes the tool lightweight and easy to clean, while the "hex rod" provides a sturdy, reliable way to advance the plunger. It is the standard-issue tool for most 10 oz standard-sized cartridges of caulk, silicone, or adhesive.

• Dripless Mechanism: Despite its simple appearance, this model includes the essential "dripless" feature—as you release the handle, the rod slightly shifts to release pressure, preventing the material from continuing to flow out of the nozzle.

• Professional Utility: These are widely used in residential and commercial finishing. Because they are lightweight and affordable, they are often stocked in multiples for larger teams to keep at different work stations.
